To all whom it may concern:

Be it known that l, CHRISTOPHER B. MICHEL, a citizen of the United States, residing at Oilfields, in the county of Fresno, State of California, have invented certain new'and useful Improvements in Quick- Acting Retainers for Demountable Rims; and I do declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, and to the characters of reterence marked thereon, which form a part of this application.

This invention relates. to improvements in retainers used for fastening demountable with no tendency to loosen unless purposely loosened in order to remove the rim. The Wedges are quickly and easily removed from the retainers by means of a tool especially adapted for the purpose and an entire set i of retainers can be released from a rim in a very few seconds.

A further produce a simple and inexpensive device and yet one which will be exceedingly usefulfor the purposes-for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters or reference indicate the corresponding parts in the several views,

Figure 1 is a side elevation of a portion of a vehicle wheel showing a rim held in place by means of my improved retainers. Fig is a s ctiona-l view taken on a line Fig. l with the wedge removing tool in position. Fig. 3 is a side elevation of felly of motor vehicle wheels,

object of the invention isto the retainer box showing the retainer there in. Fig. 4 is a front view of the same. Fig. 5 is a plan view of the wedge removing tool.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the telly of the wheel and the numeral 2 the demountable rim.

My improved retainer comprises primarily a receiving box having a securing bolt 4 by means of which the box 3 is see cured to the Belly 1, the said. box 3 also having a reinforced plate 5 which extends underneath the telly and forms a brace or reinforcement for the box 3 and also a point ojftbearing for the removingtool 'as will rsently appear.

The box 3 is inclosed on all sides, but two of its sides at theupper end, as at 6, are cut away to form a clearance for the, dropp ng I of the retaining mem er will presently be noted.

The retain ng member comprises a beveled body '2' having 'a projecting wedge 8 'arranged to extend between the deniountable rim 2 and the fixed rim 2 on the telly 1. On the upper end of the retainer 7 are projecting pins 9 having downwardly extend-- -ing linger gripslfi which normally project outside of the box 3 where they be read: ily grasped. The wedge 8 is normally held in position. between the rims. 2 and 2 by means of a wedge-shaped bindinggbloclr 11- which engages the retainer 7 and binds be tween the said retainer 7 and one of the sides or" the box 3, it being held normally in such binding position by means. of a strong spiral spring 12 interposed between the bottom. the block ll and the bottom of the box On the block 11 is a pin 13 which extends through the spring 12 and through the bot tom of the box 8,-which pin is provided on its outer end with a shoulder or nut spaced normally from the bottom of the a box 3, i

To release the wedge 8 from engagement between the rims 2 and 2 I provide a tool 15 having an upwardly projecting end and an elongated slot 1'? terminating in a 1' circular openin 18. By means oi"- the opening 18 the tool "ray be inserted over the nut ll, the pin 13 then being advanced nto the slot 1.? which is of a lesser width than the diameter of the nut 1%,,wherenpon the nut 14- be, brought into engagement with the tool 15. Theend 16 is then brought into contact with the brace'5 and by exertlIlg downward pressure on the tool 15 this will cause the same to act as a lever against the nut 14 which will pull the pin 13 and block 11 downward against the spring 12 and release theblock 11 from the retainer 7 The finger grips 10 are then grasped and the retainer 7 placed within the box 3, the wedge 8 engaging a notch 19 in one side of the box 3 to hold it from getting in the way of the rim 2. The rim 2 can then be readily re moved. After the retainer is removed from between the rims and placed within the box 3 and the tool is removed the block 11 will bind against the retainer to prevent its drop ping out while the rim is being changed. The nut 14 is held on the pin 13 by means of a counter pin l4 or other suitable retaining means. The space Gallows of the dropping of the retainer into the box 3, the

' .pins 9 and grips 10 then projecting adjacure by Letters Patent is:

'cent the sides of 2s readily be seen that I have I of the device,

the box as is apparent. From the foregoing description it can roduced such a device as substantially fulfi s the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims.

Having thus described my invention what claim as new and useful and desire to se- 1. A retaining member'for demountable rims comprising a box, a wedge arranged to I rim, a spring engage the rim and having a retaining body projecting within the box, and a spring pressed binding member removably arranged between the retaining body and one side of the box, as described.

2. A retaining member for demountable rims comprising a wedge arranged to engage the rim, a tapered retaining the wedge, 'a box into which the" retaining body projects, a spring pressed binding block movable in the box back of the re-' taining body a pin on the block projecting through the box, and means on the pin for engagement by a tool for pulling the binding block from engagement with the retaining body, as described.

3. A retaining member for demountable rims comprising a wedge arranged to en gage the rim, a retaining body on the wedge, a box into which the retaining body projects, finger grips projecting outside. of the box, and spring pressed means for frictionally binding the retaining body within the box tohold the Wedge against the rim, as described.

4. A retaining member for demountable rims comprising a box disposed adjacent the CHRISTOPHER B. MICHEL.
